Object Oriented Database vs Relational Database
Kintetsu
(Transportation, Logistics)
Kintetsu, a $2B company in Japan, models the Japanese railway system using an ODBMS.
Each train is an object, as are platforms, switches, tracks, traffic, etc. The system allows dynamic modeling of changes
due to rush hour, holidays, extra load on the electrical supply grid, etc. It's been in production for several years. The
developers have reported in published papers that it was developed in only 6 months, a fraction of the time that would
have been needed to decompose all the objects into tables. They're now reusing some of their objects for a trucking
system. |
